The present invention relates to metal shaping tools or machines andmore particularly to a device for the shaping or re-shaping of fendersor the like.

An object of this invention is to provide a sheet metal shaping meanswhich has been particularly designed for the purpose of ire-forming orreshaping fenders, the device embodying means whereby the metal may bere-shaped on a straight line or on a curve.

Another object of this invention is to provide a device of this kindwhich is so constructed that it can be used with fenders having arelatively deep side flange, the device being capable 1 of re-shapingthe inner portions of the fender and eliminating the necessity ofhammering or otherwise forcing out dents or the like in fenders.

The above and various other objects and advantages of this inventionwill in part be described and in part be understood from the followingdetailed description of the present preferred embodiment, the same beingillustrated in the accompanying drawings wherein:

Figure 1 is a detail front elevation of a device constructed accordingto the preferred em. bodiment of this invention, showing the pair ofbending rollers in operative position.

Figure 2 is a similar view with a part of the front frame removed andshowing the bending rollers in another position.

Figure 3 is a sectional view taken on the line 3-3 of Figure 1.

Figure 4 is a detail side elevation partly in section and takensubstantially on the line 4--4 of Figure 1.

Referring to the drawings wherein like numerals of reference designatecorresponding parts throughout the several views, the numeral 10designates generally a frame structure which is substantially T-shapedin transverse section and provided adjacent the upper portion thereofwith a hand grip 13. This frame 10 comprises an upper leg 11, a verticalleg 12, and a third leg 14, which is positioned on an acute angle to thevertical leg 12 and extends in the direction of the upper leg 11. Thelower leg lei terminates at its upper end in a pair of spaced ears 15between which a shaping roller 15 is rotatably mounted. The shapingroller 16 is mounted on a pivot 17 engaging the spaced ears 15. Theperipheral surface of the fixed roller 16, in'the present instance, isconvex so that this roller may engage the concave under surfaces of afender or the like. A vertically disposed guide 18 is secured to theforward end of the upper armor frame member 11 and is also secured tothe forward end of the hand grip 13. The guide 18 extends longitudinallyof the frame 10, the purpose for which will be hereinafter described. Inthe present instance, these frame members are formed integral one withanother so that a relatively strong frame will be provided. The guidemember 18 has a flat front face end the vertical edges of this guidemember 18 may be either square or V-shaped, depending only upon the typeof guide which may be desired.

A slide or carriage, generally designated as 19, slidably engages theguide 18 and is movable longitudinally of the frame 10, and is adaptedto be held in adjusted position on the guide 18 by means of a handoperated screw 20 having a wheel or operating member 21 secured thereto.The upper end of the carriage 19 is provided with a rearwardly extendinglug 22 through which the screw 20 projects, and the screw 21) isrotatably mounted in this lug 22 so that as the screw 29 moves relativeto the guide member 13, the screw 20 will carry therewith the carriage19.

A pair of rollers 23 and 24 are rotatably carried by a yoke 25, which isswingably mounted on a pivot 26 secured to the carriage 19 adjacent thelower edge thereof. These rollers 23 and 24 are positioned for coactingrelation with the lower roller 16, and when it is desired to re-shapesheet metal or the like, these rollers 23 and 24 may be positioned withthe axial center thereof on opposite sides of the axial center of thelower roller 16. The axial center of the lower roller 16 is disposedsubstantially coplanar with the longitudinal axis of the frame 10. Thelength of the frame 10 is shown in Figures 1 and 2 and the longitudinalaxis is a line drawn vertically through the frame, as disclosed inFigures 1 and 2.

An arm 2'? integral with the yoke 25 and extends along the front face ofthe carriage 19. This arm comprises a means whereby the two rollers 23and 24 may be held in laterally adjusted position relative to the lowerroller 16, and in order to hold the rollers 23 and 24: in adjustedposition on the pivot 26, I have provided a holding member in the formof a bar 28, which is secured. to a pin 29. The pivot or pin 29 ispivotally secured to the upper end of a bracing frame 30, whichcomprises a substantially iJ-shaped upper portion 31 and a V-shapedlower portion 32, which is integrai with the upper portion 31.

The frame 30 is mounted on outstanding pins or posts 33, there being onepost on each side of the carriage l9, and the convergent end of theframe 30 engages the post or pin 26 and holds the yoke 25 againstlongitudinal movement on this post 26. The pin 29 has a bar 34 extendingtransversely therethrough which constitutes an operating member so thatthe holding member 28 may be swung to the desired position. The frame 30is cut out, as at 35, and the pivotal pin 29 is provided with a stop 36engaging in the cut out portion or notch 35, thereby limiting theswinging movement of the holding member 28.

In the use and operation of this device, the frame 10, which has thearms 12 and 14 positioned on an acute angle, is adapted to be disposedwith the roller 16 on the lower side of the fender and the two rollers23 and 24 on the upper side. Turning of the hand wheel 21 will adjustthe rollers 23 and 24 relative to the lower roller 16, so that thislower roller 16 will press the metal between the two rollers 23 and 24.The handle or grip l3 and the lower end of the frame 10 can then begrasped and the device rolled over the fender or metal, which operationwill act to bend the metal on an are.

If it is desired to straighten the metal, the position of the frame canbe reversed with the two rollers 23 and 24 engaging on the concave sideof the metal and the roller 16 on the convex side. The foregoingprocedure will apply to sheet metal such as fenders or the like, whereit is desired to roll the metal on a curvature, and in order to do this,the two rollers 23 and 24 will be in the position shown in Figure 1,namely, on opposite sides of the axial center of the lower roller 16.

However, where it is desired to shape the metal without bending it on acurvature, the arm 27 can be swung to the opposite side of the carriage19 or, in the present instance, to the left, which movement will swingthe yoke 25 and raise the roller 24 while lowering the roller 23 into aposition substantially with the axial center thereof alining with theaxial center of the lower roller 16 and with the longitudinal axis ofthe frame 10. In this position, the two rollers can be engaged with themetal and slight dents or the like can be removed from the metal or themetal otherwise re-formed and the roller 24 will be disposed ininoperative position laterally of the longitudinal axis of the frame 10.

By providing a carriage operating member in the form of a screw 20 whichis threaded into the frame 10 and which swively engages the carriage 19,this carriage 19 can be adjusted to any desired position relative to thelower roller 16 and the carriage will be locked in its adjustedposition. By providing at least three rollers, two of which are mountedon the carriage, which can be adjusted to any desired position relativeto the fixed or lower roller, the metal can be re-formed withoutpounding and the surface of the metal is, therefore, left smooth whenthe metal has been reshaped. Preferably, the rollers 23 and 24 areconstructed with a fiat peripheral surface although I, of course, do notwish to be limited to the particular shape of these rollers 23, 24 and16, as they may be of any other configuration, depending only upon thecharacter of metal which it is desired to work upon and theconfiguration which it is desired to form from the metal.
